I have also had this issue.. what i have observed is that the problem only began occurring when I inserted my 32gb micro sd card and had the camera app set to store on the said sd card instead of the internal memory. The problem would be that sometimes, upon opening the camera app, you would see a black screen for a few seconds and then the phone would reboot. I have also noted that the camera app takes a little while to start when it does work.
I have subsequently set the camera app to store on the internal memory and i have not had the problem since and the camera app opens noticeably faster. I believe this is a software issue. This is purely speculation on my part but i think it has to do with the speed of the memory card. If it is not of the highest class, it takes too long for the camera app to read and the app hangs and the phone reboots. It also think this is the reason why the camera takes so long to start when it does work.
Hope this helps

I have the same problem, with the camera app, I use an 32 GB Class 10 by SanDisk. Takes time to open Camera app.
I think it is a problem with the SD card, and have asked for replacement.
Also at times when using the camera, with the flash set to Auto, I get an message saying 'Device temperature too high, cannot use flash'. - This may be related or a completely separate issue..
I have also noticed the random restart, with other apps too. Is everyone getting this with only with the camera app?? Or are other apps also causing the problem.

I also have this problem tried latest mdk firmware and still hapens

After changing the location of the files the problem persists. I even removed the Class 10 32gb sd card and it still reboots then accesing the camera.
Hope is a sofrware bug they can fix soon. Cant believe I traded a Htc One for this alpha phone.
Thanks guys

same here, sometimes when I open the camera app my S4 freezes for few seconds and then reboots, not mentioning the overheating problem.
Samsung should release an update or something, it better be a S/W issue otherwise I will kill someone.

Do you have problems running Antutu benchmark?
I have the same symptoms as you describe and the one thing that makes my phone restart every time is running the Antutu CPU benchmark.

Everything is stock and yes the phone likes to reboots when I start the camera app. Not every time but like once out of 2 times

Hi MoHeadGeek,
Do you have any update on that?

Any updates on the reboot issue when using the camera? It is really annoying

Same here. I don't know if I should change my phone or it's just a software bug that they will solve soon...
For me, it also freezes+rebooted while in the gallery or even launching some app.

If everything is stock, unmodded, and you installed all available updates from Samsung I would go get a replacement.

If your phone restarts when you start the Camera it is a software issue
It happens due to low RAM [the irony that it is in S4 -_-]
They should fix it soon but if you need to immediately then go to development options, scroll all the way down and keep Max tasks to 4.
Read it somewhere it works
But I think you have to set again after maual reboot

I installed the german update and it fixed the problem.
The developers options didn't work for me when I was with the stock rom.

Just bought my S4 and I am having the same problem, did you happen to find out the cause of this?

Rebooting when opeining the camera is a common bug. But random freezing and reboots is not a bug.
For the first issue, I will wait for 1 software update from Samsung to fix the camera, but for the latter I would highly recommend exchanging your phone.

Make sure your kernel and software match each other, e.g. you are not running an older kernel than you should be, for example MDE kernel with MDK software, mixing can cause these type of issues.

S4 keeps freezing on the keyboard and is laggy

Recently my Samsung galaxy S4 keeps freezing on the keyboard and then the phone stops working and freezes for at least 5 seconds before it even responds to anything and is also quite laggy at times too. Anyone else having same/similar issues?
I'm running the latest stock version of Android 4.4.2

Lock ups using Snapdragon Note 4

Recently I've been getting lots of hangs when using my note 4.. it's only a couple weeks old.
Sometimes when typing the system just freezes or types really slow, other times when scrolling through Facebook or Skype.
Also when playing music the music stop playing for a couple of seconds then resumes. Streaming does the same.
Using different apps to play music does nothing.
Has anyone else had similar problems?
What would you recommend? Warranty return?
Reset all data?
Love my note 4 but is getting on my nerves slightly now! :banghead:
